Switch case having flanges that fold over clearance between case and cover
A switch device has an operating unit, a circuit board having a contact unit that is switched according to the operation of the operating unit, a case having the operating unit at an upper section thereof, an opening at a lower section thereof, and the circuit board inside thereof, and a cover that is fitted to the opening of the case to close the opening. A thin hinge and a flange continuous to the hinge are formed integrally with the case along a side wall at a lower end of the side wall of the case. The flange is folded and bent on the hinge, so that a clearance defined between the case and the cover is covered with the flange.
1. A switch device comprising:
an operating unit;
a circuit board having a contact unit that is switched according to operation of the operating unit;
a case having a plurality of side walls which form an opening within which the operating unit is arranged at an upper section thereof, and the circuit board is arranged at a lower section thereof; and
a cover that is fitted to the opening of the case to close the opening, such that a flange integrally formed with the case through a continuous hinge along a lower end of each side wall of the case, enables each flange to be folded and bent along the respective hinge, such that a clearance defined between the case and the cover is covered with the flange.
2. The switch device according to claim 1 ,
wherein a hook having elasticity is formed on the cover, such that the folded and bent flanges are securely hooked on the hook.
3. The switch device according to claim 1 ,
wherein an upper surface of each hinge projecting from the side wall has a slope.
4. The switch device according to claim 3 ,
wherein a hook having elasticity is formed on the cover, and further, the folded and bent flange is securely hooked on the hook.
5. The switch device according to claim 1 ,
wherein
wherein ends of the flanges are superimposed on the ends of adjacent flanges in a state in which the flanges are folded and bent.
6. The switch device according to claim 5 ,
wherein a hook having elasticity is formed on the cover, and further, the folded and bent flange is securely hooked on the hook.
7. The switch device according to claim 5 ,
wherein a recess is formed at a point where ends of the flanges are superimposed one on another.
8. The switch device according to claim 7 ,
wherein a hook having elasticity is formed on the cover, and further, the folded and bent flange is securely hooked on the hook.
9. The switch device according to claim 7 ,
wherein a hook having elasticity is formed on the cover, and further, the folded and bent flange is securely hooked on the hook.
